Tread Perilously continues its tour of duty among the stars with the Farscape episode "Taking the Stone."

When Chiana learns her brother is dead, she arranges to escape her grief on a cemetery planet. There, she finds a civilization of cave dwellers who die when they turn twenty-two, but somehow stave off death by taking part in "the Gathering." Considering that the ceremony will either kill her or help process her brother's death, Chiana decides to take part in the Gathering. Crichton discovers that the magic science behind the Gathering may actually be the reason they perish so young. Can he save the planet's inhabitants and Chiana at the same time? Meanwhile, Rigel is warned not to steal from the dead, but gives into his desire for treasure. It appears to unleash a specter upon the ship.

Erik compares Farscape's production values to some of the worst art direction on the new and old Doctor Who. He also refuses to address Rigel as anything but a Koozbanian. Justin asserts that most sci-fi series feature space whales. He also tries to imagine an Orc/Dalek hybrid. Both take a bold stance against the Union of the Snake. Erik creates Deadbrew -- an alcoholic beverage made with the remains of the dead and Justin tried to explain why one character on Farscape has too much design.
